Currently, the application of power batteries is more widespread from the development of market situation. The power battery is not only applied to energy storage power supply systems such as hydraulic power, firepower, wind power and solar power stations, but also widely applied to electric vehicles such as electric bicycles, electric motorcycles, electric automobiles, and the like, and a plurality of fields such as military equipment, aerospace, and the like. With the continuous expansion of the application field of the power battery, the market demand of the power battery is also continuously expanding.
The battery cells of the power battery can adhere to some impurities during the production, storage and transportation processes, for example, sheets used for forming the battery cells such as pole pieces can adhere to some impurities such as dust more or less during the production, storage and transportation processes. For example, in the processing process of the pole piece, dust falls off in the cutting process and the like, and the fallen dust particles adhere to the surface of the pole piece to form impurities, so that the safety, quality and service life of the formed battery cells are influenced. For another example, the isolating film used for forming the battery cells can be also used for adhering some dust during the production, storage and transportation processes, so that the dust removal technology of the battery cells is critical under the condition of no link to different links.
The development of the dust removal technology needs to consider various design factors, such as dust removal strength, dust removal effect, cycle life and other performance parameters, and also needs to consider the safety performance.
Referring to fig. 1, fig. 1 is a state diagram of a dust removing device in the prior art. The applicant has found that existing dust removal techniques, even if a dust removal device is provided in a battery cell, present a risk of the sheet 100 for forming the battery cell adhering to the impurities 300. The applicant has further studied and found that the current dust removing apparatus generally uses the air blowing module 400 to blow compressed air obliquely forwards, the compressed air applies an air blowing force F0 obliquely downwards to the impurities 300 on the sheet 100, the air blowing force F0 generates vertical component force Fy, and the force Fy is vertical to the coating of the sheet 100, if dust particles are foreign matters similar to metal burrs, the hardness of the dust particles is far greater than that of the coating, and the dust particles are relatively sharp, and when the force Fy is large enough, the dust can pierce the coating, be inlaid on the coating, not be blown off, and when the battery cells are finally molded and hot pressed, the sheet 300 is pierced to wait for cleaning objects, and the safety of the objects is damaged.
And, the blowing force F0 generates a horizontal Fx and a vertical component force Fy, the included angle between the blowing force F0 and the horizontal is theta, and theta is more than or equal to 0 DEG and less than or equal to 90 DEG, and the friction element of the coating on the impurity 300 heel 100 is mu, and the separation resistance F of the impurity 300 heel 100 is assumed Adhesive tape Friction force between the impurity 300 and the sheet 100 is f=μ×f=μ×f0×sin θ, force F for separating the impurity 300 from the coating layer Closing device Can be obtained according to formula (1):
F closing device ＝Fx-f-F Adhesive tape ＝F0(Cosθ-μSinθ)-F Adhesive tape (1)
As can be seen from the formula (1), the force component Fx of blowing off the dust particles also works against the friction force F, and the greater the blowing force F0, the greater the friction force F, which results in a deterioration of the blowing efficiency, and the adhesion force F of the impurity 300 Adhesive tape When F0 (Cosθ -. Mu.Sinθ) is not smaller, the impurity 30 is not blown off. Therefore, the existing dust removing technology has a risk of poor dust removing effect and damaging the object 300 to be cleaned.
In view of this, this application embodiment provides a dust collector and battery production system, can satisfy the cleaning demand, and dust removal effect is good and can not harm the object of waiting to clean.
